H3C 配置vlan及vlan间路由

配置vlan

实验目录

一.配置vlan、trunk

1.配置H3C1的vlan，及vlan查看命令！！

  [H3C1]display vlan

  [H3C1]display vlan all

  [H3C1]display port trunk

  [H3C1]display interface e0/4/3

2.配置H3C2的vlan

3,解决默认只允许vlan1通过trunk链路

[H3C1-Ethernet0/4/3]port trunk permit vlan all

4.gvrp相当与Cisco的VTP服务

 

 

二.vlan间路由

1.三层交换trunk和hybrid

2.单臂路由

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

一.配置vlan、trunk

1.配置H3C1

[H3C1]int vlan 1                 //为vlan1配置ip地址

[H3C1-Vlan-interface1]ip add 1.1.1.1 255.255.255.0

[H3C1-Vlan-interface1]un shut

 

[H3C1]vlan 2                   //创建vlan2

[H3C1-vlan2]q   

[H3C1]int vlan 2                //为vlan2配置ip地址

[H3C1-Vlan-interface2]ip add 2.2.2.2 255.255.255.0

[H3C1-Vlan-interface2]un shut

[H3C1-Vlan-interface2]q

 

[H3C1]int e0/4/3               //开启trunk链路

[H3C1-Ethernet0/4/3]port link-type trunk

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

粗略的查看有设备上有几个vlan

[H3C1]display vlan   

 Total 2 VLAN exist(s).

 The following VLANs exist:

  1(default), 2

 

详细的查看设备上vlan的情况

[H3C1]display vlan all

 VLAN ID: 1                              //vlan1的详细信息

 VLAN Type: static                         //vlan属于静态的，也就是说是手工创建的

 Route Interface: configured

 IP Address: 1.1.1.1

 Subnet Mask: 255.255.255.0

 Description: VLAN 0001                       //对vlan的描述

 Broadcast MAX-ratio: 100%                   //广播包在vlan链路占的百分比，可改

 Tagged   Ports: none                        //标记的，如果串行接口不在此vlan中，                                                                        那个接口将会出现在此处！

 Untagged Ports:                             //可以说是属于本vlan的接口

    Ethernet0/4/0            Ethernet0/4/1            Ethernet0/4/2           

    Ethernet0/4/3            Ethernet0/4/4            Ethernet0/4/5           

    Ethernet0/4/6            Ethernet0/4/7           

 

 VLAN ID: 2                 //vlan2的详细信息

 VLAN Type: static

 Route Interface: configured

 IP Address: 2.2.2.2

 Subnet Mask: 255.255.255.0

 Description: VLAN 0002

 Broadcast MAX-ratio: 100%

 Tagged   Ports: none

 Untagged Ports: none

 

查看vlan接口状态，可以看到vlan2是down的，原因是：默认trunk只为vlan1服务！！

[H3C1]display ip interface brief

*down: administratively down

(s): spoofing

Interface                                Physical   Protocol   IP Address     

Ethernet0/1/0                              up         down     unassigned     

Vlan-interface1                            up         up       1.1.1.1        

Vlan-interface2                            down       down     2.2.2.2

 

查看设备上开启trunk的端口，PVID属于哪个vlan，允许通过trunk的vlan！此时只有1！

[H3C1]display port trunk

Interface            PVID  VLAN passing

Eth0/4/3             1     1  

 

查看trunk端口

[H3C1]display interface e0/4/3

部分显示省略

Port link-type: trunk

  VLAN passing  : 1(default vlan)             //默认只有vlan1通过

  VLAN permitted: 1(default vlan)             //默认只允许vlan1通过

  Trunk port encapsulation: IEEE 802.1q       //封装类型只会是IEEE802.1q

 

2.配置vlan2

[H3C2]int vlan 1

[H3C2-Vlan-interface1]ip add 1.1.1.2 255.255.255.0

[H3C2-Vlan-interface1]un shut

[H3C2]vlan 2

[H3C2-vlan2]q

[H3C2]int vlan 2

[H3C2-Vlan-interface2]ip add 2.2.2.3 255.255.255.0

[H3C2-Vlan-interface2]un shut

[H3C-Ethernet0/4/3]port link-type trunk

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

3.解决默认只允许vlan1通过trunk链路

虽然配置完毕但是此时vlan2的接口是down的，原因上面已经看到，是默认只能vlan1通过trunk，这点是和Cisco不同的地方。

我们要在的是允许所有的vlan通过trunk链路

 

[H3C1]interface e0/4/3

[H3C1-Ethernet0/4/3]port trunk permit vlan ?

  INTEGER<1-4094>  VLAN ID

  all              All the VLANs

 

[H3C1-Ethernet0/4/3]port trunk permit vlan all

 Please wait...

%Nov 18 19:59:07:453 2010 H3C1 IFNET/4/LINK UPDOWN:

 Vlan-interface2: link status is UP

%Nov 18 19:59:07:453 2010 H3C1 IFNET/4/UPDOWN:

 Line protocol on the interface Vlan-interface2 is UP ........................................ Done.

[H3C1-Ethernet0/4/3]         //此时vlan2接口就开启了

 

 

[H3C2]interface e0/4/3

[H3C2-Ethernet0/4/3]port trunk permit vlan all

 Please wait...

二.vlan间路由

 

1.三层交换--trunk和hybrid

首先介绍trunk

通过trunk使用三层交换实现vlan间路由是很简单的，只需要开启trunk链路并允许相应vlan通过即可！与Cisco不同，不需要开启路由功能！！！！

然后是hybrid

Hybrid是h3c的，下面的实验就是hybrid的应用。

实验拓扑

实验环境：

Pc0属于vlan2  网关：192.168.2.254

Pc1属于vlan3  网关：192.168.3.254

Sw1上    vlan2:192.168.2.254         sw2上  vlan3:192.168.2.252

          Vlan3:192.168.3.252                vlan3：192.168.3.252

 

实验步骤：

创建vlan并把相应的接口加入到vlan中

[sw1]vlan 2

[sw1-vlan2]vlan 3

[sw1-vlan3]vlan 2

[sw1-vlan2]port e1/0/6

 

为vlan设置ip地址

开启hybrid的混杂链路类型

设置vlan2、3不打标签！看同一台交换机上不同vlan能否通信

                       看不同交换机上的不同vlan能否通信

 

 

 

 

 

实验环境如图

实验步骤：

创建vlan并把相应的接口加入到vlan中

[sw1]vlan 2

[sw1-vlan2]vlan 3

[sw1-vlan3]vlan 2

[sw1-vlan2]port e1/0/6

[sw1]int e1/0/2

[sw1-Ethernet1/0/2]port link-type trunk

[sw1-Ethernet1/0/2]port trunk permit vlan all

[sw2]vlan 2

[sw2-vlan2]vlan 3

[sw2-vlan3]port e1/0/6

[sw2-Ethernet1/0/2]port link-type trunk

[sw2-Ethernet1/0/2]port trunk p vlan all

 

为vlan设置ip地址（不设置应该可以）

 

设置路由器--开启主接口

[H3C]int e0/0

[H3C-Ethernet0/0]un shut

创建子接口-ip-封装类型+对应vid

[H3C]int e0/0.1

[H3C-Ethernet0/0.1]ip add 192.168.2.254 24

[H3C-Ethernet0/0.1]vlan-type dot1q vid 2

[H3C]int e0/0.2

[H3C-Ethernet0/0.2]ip add 192.168.3.254 24

[H3C-Ethernet0/0.2]vlan-type dot1q vid 3

 

[H3C]display ip int b

*down: administratively down

(s): spoofing

Interface                                Physical   Protocol   IP Address

Aux0                                       down       down     unassigned

Ethernet0/0                                up         down     unassigned

Ethernet0/0.1                              up         up       192.168.2.254

Ethernet0/0.2                              up         up       192.168.3.254

Ethernet0/1                                down       down     unassigned

Serial4/0                                  down       down     unassigned

 

[H3C]int e0/0

[H3C-Ethernet0/0]ip add 192.168.1.1 24

 

 

Sw1上开启与路由器相连的trunk链路--允许所有

[sw1]int e1/0/12

[sw1-Ethernet1/0/12]port link-type trunk

[sw1-Ethernet1/0/12]port trunk permit vlan all
